Caption

Satellite radar image of the magnitude 6.0 South Napa earthquake. The "fringe" rainbow pattern appears where the earthquake deformed the ground's surface, with one full cycle of the color spectrum (magenta to magenta) showing 3 centimeters of change. Satellite data like this can now be used to give researchers an understanding of an earthquake and its impacts within days.
